To all 'whom t may concern.'

l yBe it known that I, WILLIAM A. EVERITT, va subject of the King of Great Britain, re-

siding at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Snowplows; vand I do declare the following to bea full, clear, and exact description of I the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

This invention relates to an improved snow plow ofthe internally heated type and one object of the invention is to provide a plowy so constructed that it may be connected with-a car and preferably mounted VVin front of the same, means being also pro- ,Y vided to permit theplow to have vertical movement so thatit will accommodate itselfV to unevenness in a track and ,so that the plow may be swung upwardly to an inoperative' Y positionwhen so desired.

Another object of the inventionis to so `construct thisplow that the heating means for the same may consist of conductor. pipes and discharge or burner nozzles positioned within the plow, the plow being divided into compartments through which the lfuel and air pipes.. will pass and .in which the nozzles will be positioned.

Another object of the invention is to so ,construct thisk plow that the products of combustion may pass out of the same andto further s0 construct it thatready access may be had to the .interior of the plow for cleaning and repairing the same.

Another object of the invention isto so rconstruct this plow that it may be connected with the rear portion of ak car for trailing behind the car if so desired.' v

Another object of the invention isto provide a plow of this character `which will be comparatively. simple in construction and strong andv durable.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view in side elevation showing the plow connectedwith the forward end of a car. M

Fig. 6 is a longitudinally extending sec# tilonal View taken horizontally through the pow.

- Fig. 7 is a transverse sectional view taken along the line 7-7 of Fig. 5.

` 8 isV an enlarged fragmentary sectional view taken longitudinally through the plow along the line 8-4-8 of Fig. 6;

This plow which is indicated in general .bottom thus permitting the plow to move along a track and slidev easily through or over snow upon the track. Transversely ex# tending supportingfrai'nes 6 are provided iii this housing and partitions 7 which extend horizontally and are archedas'shown in Figs. `'and 8 are provided in the housing .and carried by the partitions so that theV housing isdivided into a plurality of compartments 8. These compartments are in ytheir turn provided with dividing walls 9 thus providing auxiliary compartments 8. Itshould be noted that the yauxiliary com# partment of one compartment or chamber 8 is positioned at the opposite side of the plow 4from the auxiliary compartment of the ad-V jacent compartment 8 for ya hereinafter brought out.

This plow is provided in its upper wall with doors `l() which may be opened when it is desired tohave access to the interior' of the housing and these doors and the upper wall of the housing are provided with open'il ings having hbods 11 positioned in front of them so that the products of combustion may escape from the housing and be directed rearwardly' as ythey pass out of the purpose to be housing Openingsv are provided in the ,para "titions 7 so that the products of combustion may pass from ybeneath the partitions into the upper portion'of the plow housing and .out through the openings in the upper wall thereof. In order to permit'the'plow to have vertical movement and be swung to an inoperative position, there has `been pro'- vided beams 12 which are pivotally connected with the sides of the car 2 as shown at 13 and have their forward ends connected with the arms 14 which extend forwardly in converging relation and are connected with a hanger shaft 15 which extendsV through the slot -16 formed inz'the ears 17 which extend longitudinally of. the plow. It will thus be seen that with the plow in the position for use,the plow. may have vertical movement to follow irregularities ,in

the tracks and that by swingingthe beams 12 upwardly, the plow Vmay lbe swung upwardly to an inoperative position.\ Inorder to swing the beams upwardly, these beams have their rear endportions provided with eyes 18 which are connected with cables 19 wound upon the drums 20. Byrotating the v drums so that thel cables are unwound from` one set and wound upon thev lsecond set, the

forwardk end portion of the plow*l sothat if desiredthe plow may be connected with any suitable drag means atthe rear portion of a car and thus the plow drawn after the car,

instead of being pushed in front of the same.

vThis plow'is to be so mounted thatl as it moves along the tracks, the plow may serve to push the major portion ofthe snowto the sides of the tracks and also serve to melt` Y snow and ice which may remain uponthe' tracks beneath'the plow and thus entirelyA free` the tracks from snow. They heating means employed is inthe form of liquid fuel burners having nozzles which. are positioned inthe compartments 8 in operative,y

relation to the openings 2?).formed in the partitions 9. It will thus be seen that the arnefrom the nozzlesv or burners 22 will be directed through the openings 23 into the compartments 8. It willbe seen from an inspection ofv Fig. 6 that alternate burners are positioned upon opposite sides ofthe plow and therefore the vplow will be very thoroughly heated. In order to provide oil and compressed air to the burners'22 there has been provided pipes24 and 25 which'eXf.:

tend longitudinally through the plow and are provided with branch' pipes 26 and 2'( connected with the burners. The specific construction of the burners hasvnot been shown asany burner` of the v.type employing fuelroil and compressed air may be .em-`

ployed. These pipes 24y and 25 extend 4through the rear` portion of the plow and are connected with feedpipes 28 and 29 which will lead to suitable reservoirs for the liquid fuel and compressed air.

When this plow is in use, it will be connected with the car in the manner shownv in Figs. 1 and '2 and as the car proceeds along a track covered with snow, the plow will move the snow transversely of the "track A certain portion of the snow will tendy to pass under the plow., and as jthis snowgandice comes in contact with the hot plow the snow and ice will be melted causing the tracks to be thoroughly cleared of Y snow and ice. By having the plow mounted by hinges and having the arms' 14 slidably connected with theplow, the plow may have Vertical movement `thus permitting it tofollow irregularities in the track. When1 it is desiredfto swingthe plow upwardly to the 'inoperativepositiom it is simply 'necessary to swing the beams 12 upwardly and thus cause the'plow tobedrawn upwardly to the inoperative position where it will be held ,out of engagementwith the track.

Iclaim': Y V1. A snow plow adapted for hinged connection Vwith la car for, vertical swinging cmov'ement, beams vadapted to begconnected withacar for vertical swinging movement,
